|Equipment||Pistol, revolver or rifle|
Metallic silhouette shooting is a group of target shooting disciplines that involves shooting at steel targets representing game animals at varying distances, seeking to knock the metal target over. Metallic silhouette is shot with large bore rifles fired freehand without support out to 500 meters, and with large bore handguns from the prone position with only body support out to 200 meters. Competitions are also held with airguns and black-powder firearms. A related genre is shot with bow and arrow, the metal targets being replaced with cardboard or foam. The targets used are rams, turkeys, pigs, and chickens, which are cut to different scales and set at certain distances from the shooter depending on the specific discipline.
Metallic silhouette is descended from an old Mexican sport, dating back to the early 1900s, where live game animals were staked out at varying distances as targets. By 1948, metal cutouts of the animals were used instead of live animals, birthing 'siluetas metalicas'.  The first metallic silhouette match was held in Mexico City. Because of the sport's Mexican roots, in the United States the silhouettes are often referred to by terms from several varieties of American Spanish, namely gallina (chicken), jabali (pig), guajalote (turkey), and borrego (ram).
The first silhouette range constructed in the United States was in 1967 at Nogales, Arizona. Growth was steady until 1973 when the NRA become involved in the sport. By the mid-1980s it was the fastest growing gun sport in the United States. It is a sport that appeals to hunters, plinkers, and serious target shooters without the financial barriers of some other competitive shooting sports. Jim Carmichel called it the 'common ground on which to unite'.
The International Metallic Silhouette Shooting Union (IMSSU) is the international federation controlling metallic silhouette competitions for both rifle and pistol. There are also two major US-based bodies; the National Rifle Association covers all types of silhouette shooting in the United States, and the International Handgun Metallic Silhouette Association (IHMSA), founded in 1976. There are some minor differences between the international federation's IMSSU rules and those of the NRA and IHMSA, but it is generally possible to compete in all with the same equipment.
Silhouette shooting is growing in popularity in Canada. Silhouette Canada (S.R.A.C.) is the governing body for rifle metallic silhouette target shooting in Canada. S.R.A.C. sanctions the Canadian National Rifle Silhouette Championships hosted each year by one of the participating provincial silhouette associations. The Canadian Nationals adhere to NRA silhouette rules and regulations.
Targets are set up in groups of five of each kind, with a silhouette's width between targets, laid out at the required distances for the given match. Each group of targets must be shot left to right; if a target is missed then the next shot is taken at the next target. Any target hit out of order is considered a miss. Targets are engaged in order of distance: chickens, pigs, turkeys, rams. The target must be knocked down or pushed off the target stand in order to score a hit; even a shot ricocheting off the ground in front of the target will count if it takes down the correct target. Shooters are allowed to have a spotter with them, who watches where the shots land and advises the shooter on corrections to make.
All disciplines require a minimum of 10 shots at each type of target, for a minimum of 40 shots per match; normal matches are 40, 60, 80, or 120 shots. To score a hit, the target must be knocked off its stand, so each cartridge used must provide sufficient momentum to knock the heavy metal targets over. Scores are recorded as the number of hits per rounds fired, so 30 hits with 40 shots is a score of 30x40=1200.
A tie can be broken in one of two ways: a sudden death shoot-off, used at all national and large regional competitions and for the overall match winner. Master Class and AAA shooters shoot at turkeys, AA Class shoot at rams, A Class shoot at chickens and B Class shoot at pigs. To save time and effort, a reverse animal count can also be used (number of hits on hardest animal to easiest), with whoever hits the most turkeys being the winner. If a tie still exists, whoever hit the most rams is the winner. This continues to chickens and finally pigs.
For IHMSA competition, tie scores are broken by either reverse animal count, or by shootoffs, as determined by the match director, however, for state, regional and international championships, shootoffs are used to determine the winners in all categories and classes. For reverse animal count, scores are compared starting at rams; the shooter with the most rams is the winner. This procedure is used sequentially down through turkeys, pigs and chickens. If a tie still exists, a shootoff is used to determine the winner. Shootoffs are in banks of five targets and can be any type or size, placed at any distance out to the maximum ram distance for the competition. Shooting strings continue until all ties are broken. Sudden death shootoffs are not allowed.
Rifle silhouette shooters generally shoot from an unsupported standing position, though black-powder rifles may use shooting sticks in some competitions.
Handgunners may be required to shoot from an unsupported standing position (two hands may be used), or from a 'freestyle' position. Freestyle includes some unusual positions, such as the Creedmore position, which is shot lying on the back, legs bent and feet flat on the ground, with the pistol resting on the shooter's right leg. In a freestyle position the pistol may only contact the shooter's body, no rests may be used (not even, in the case of the Creedmore position, the top of a boot).
There are informal matches for special classes, like cowboy rifles and pistols and vintage military surplus rifles.
All rifle shooting is done standing, with the firearm unsupported. The exception to this is black-powder rifles; the ranges are the same as large-bore rifles, but only chickens must be shot unsupported; all other targets may be shot from any position, including crossed sticks, a bench may not be used. Pistol shooting, unless in a designated standing event, can be shot from any unsupported position. Like the any-position pistol shooters, standing pistol shooters adopt odd positions in their quest for the most stable possible shooting position. Standing pistol is the most difficult discipline; no one has yet shot a perfect 40x40. Standing big-bore any-sight pistol matches are often tied with perfect scores, and decided by a tiebreaker.

|Height||28 cm (11 in)||36 cm (14 in)||58 cm (23 in)||69 cm (27 in)|
To allow shooting at ranges which may not have space for a full target layout, NRA rules allow the use of reduced scale pigs, turkeys and rams placed at the same distance as chickens. The scale is reduced proportional to the change in distance, so the targets will cover the same angular distance as they would if set up at full range. Reduced scale matches fired at paper targets are also popular for informal competitions, especially for Internet-based matches where the shooters may reside in different countries. These are generally fired with rimfires or airguns.
Targets for large-bore use are 9.5 to 13 mm (3⁄8 to 1⁄2 in) thick hardened steel; small bore targets are 5 to 6 mm (3⁄16 to 1⁄4 in) steel, and airgun targets are 3 mm (1⁄8 in) steel, although some aluminum targets are produced.
Ranges are measured in meters only. The exception is the new IHMSA air pistol discipline, which is in yards only.

Both bolt action and break action pistols are common in metallic silhouette shooting, as well as revolvers. Pistols usually either have a center grip or rear grip, and which is favored depends on shooting position and personal preference. Examples of pistols used for metallic silhouette shooting are the Remington XP-100, Thompson/Center Contender, Savage Striker and Tanfoglio Thor.
Metallic silhouette handguns most often have iron sights, although there are some national divisions where scope sights are used. Handgun scopes are usually rifle scopes with normal eye relief (especially for the standing position), but sometimes extended eye relief (EER) scopes are used (also called 'scout' sights), especially when used for a lying position.
All long range handgun metallic silhouette events are fired with targets at the distances 50, 100, 150 and 200 meters.
The four international fullbore handgun divisions sanctioned by IMSSU are: Unlimited, Production, Standing, and Revolver.
IMSSU also has smallbore variations of the fullbore classes which follow the same rules, except that the only cartridges permitted are .22 Short, .22 Long or .22 Long Rifle, that the target distances are halved, and that diopter sights are permitted in standing smallbore.
As of 2020 most competitions in the U.S. are shot under NRA or IHMSA competition rules instead of using the international IMSSU rules, except for World Championships which are held according to IMSSU rules. The NRA rules lies closer to IMSSU, since NRA is the U.S. representative of IMSSU through the United States Metallic Silhouette Association (USMSA). The National Rifle Association of America (NRA) has a total of 7 categories, which can be divided into 3 Conventional categories and 4 Unlimited categories. IHMSA has a total of 8 categories, which can be divided into 3 Production categories and 5 Unlimited categories. The NRA Conventional and IHMSA Production categories are very similar, and the same can be said for the NRA Unlimited and IHMSA Unlimited categories. There are some minor differences and overlaps between the different three different competition rulesets, with the most important outlined below.
In the NRA Conventional and IHMSA Production the handgun must be a stock, unmodified and readily available factory gun with a maximum barrel length of 273 mm (103⁄4 in). As a rule of thumb, bolt action pistols are not permitted in NRA Conventional, which excludes bolt action pistols and therefore makes revolver and break action pistols competitive. Bolt action pistols are however permitted in IHMSA Production, except in IHMSA Production Revolver which is restricted to revolers. Other differences between the classes are listed in the table below:

Metallic silhouette rifles most often have scope sights.
Anschutz is the manufacturer which totally dominates the smallbore silhouette rifle field. At the 2007 NRA Smallbore Rifle Silhouette National Championship 71% of all of the standard rifles were Anschutz rifles, 67% of the hunter rifles were Anschutz rifles.
Competitions in the United States are held by the United States Metallic Silhouette Association (USMSA), which follow NRA rules in the U.S. and IMSSU rules in World Championships.
NRA rules for high power (silhouette and hunter) permit rifles in caliber 6 mm or larger, provided no belted cartridges or magnums are allowed. Common calibers can be thought of as in the deer hunting, target shooting and bench rest range. .243 Winchester, 6mm Remington, 6mm BR, .260 Remington, 6.5mm Creedmoor, 6.5×55mm, 6.5x47, 6.5 TCU, .270 Winchester, 7mm-08 Remington, 7mm BR Remington, 7mm TCU, 7x57mm, .30 TC, .308 Winchester, and .30-06 Springfield. The limiting factor is the balance between amount of recoil and the ability to retain enough energy to knock the rams over at 500 meters.
Ear protection and eye protection is mandatory.Spotting scopes and binoculars are commonly used. Gloves are only used for extra warmth when conditions require.
Many shooters prefer to have their own personal timer to show a countdown of the remaining time of a shooting period. To aid in sight adjustment, many use a notebook or other aid to show an overview of relevant ballistics. Any tools needed for sight adjustment should be brought along. Elbow pads are commonly used to reduce impact to the elbows against the ground and recoil. A leg garther is often used to store ammunition, and a blast shield (also called leg shield) is normally used, especially for revolver shooters due to the blast from the revolver cylinder. A carrier box or shooting box can be of great help for convenient transporting of the firearm from station to station on the range.
Clothing such as commercial-type trap and skeet vests (sleeveless) and shotgun shooting shirts are permitted as well as clothing normally suitable for existing climatic temperatures. Shooting coats, unnecessarily heavy clothing, or anything that would provide artificial support such as clothing having excess padding or stiffening material or which restricts or supports the body in the shooting position may not be worn. In black powder cartridge rifle competitions only period costumes are permitted.
